tcp/ip协议报文-阿里云

四十、TCP协议的特点、TCP报文段格式和TCP的连接管理

1、TCP 协议的特点(1) TCP是面向连接(虚连接)的传输层协议； (2) 每一条TCP连接只能有两个端点，每一条TCP连接只能是点对点的，所以TCP协议不能进行广播和多播； (3) TCP提供可靠交付的服务，无差错，不丢失，不重复，按序到达；(4) TCP提供全双工...

计算机网络学习28：TCP报文段首部

同时，发送窗口的大小还取决于拥塞窗口的大小。也就是发送窗口应该从接收窗口和拥塞窗口中取小者。

网络协议报文理解刨析篇二(再谈Http和Https), 加上TCP/UDP/IP协议分析(理解着学习), 面试官都惊讶你对网络的见解（2）

拥塞控制(滑动窗口) 大小决定 min( 接收窗口决定的 , 拥塞窗口决定 (发送方发送缓冲区大小))why需要慢开始，最一开始发送方会将发送窗口(拥塞窗口的)设置的很小 ? 因为网络环境错综复杂，刚开始不清楚网络环境的好坏, 所以满开始就有点像是派...

一. 再谈HTTP再理解协议的本质: 双方的一种约定，规则，双方需要按照相同的一套处理机制(协议)进行处理应用层协议对应的是一个服务, FTP文件传输协议， NDS域名解析协议, HTTP超文本传输协议, 这些是协议同时也对应着一个服务.http协议的本质 : http协议的本质是要获得...

简述TCP报文首部字段及其作用

16位端口号：源端口号，主机该报文段是来自哪里；目标端口号，要传给哪个上层协议或应用程序32位序号：一次TCP通信（从TCP连接建立到断开）过程中某一个传输方向上的字节流的每个字节的编号。32位确认号：用作对另一方发送的tcp报文段的响应。其值是收到的TCP报文段的序号值加1。4位头部长度：表示tc...

TCP协议学习笔记、报文分析

TCP（Transmission Control Protocol传输控制协议）协议是基于IP协议，面向连接的、可靠的、基于字节流的传输层通信协议。基于IP协议：在TCP/IP协议栈中，TCP协议是基于IP协议之上传输的，TCP协议报文中的源端口+IP协议报文中的源地址+TCP协议报文中的目标端口....

在 TCP/IP 网络中，通常会用什么来描述数据报文的目的地？
